I have recognized that the Physics Properties are different to 2.81a. So I assume it's actually under development in 2.82 Alpha.

@Renderbicks Mantaflow has to bake sim data before it can play. Go to the Physics tab and hit the Bake Data button

This is not a bug, it works a bit different with Mantaflow. Make sure that you've saved your project file at least once and then open the Physics Properties and click Bake in Smoke > Cache.

yes, this is not a but, after changing mantaflow gas cache type from default to Replay, quick smoke simulation work as in previous not mantaflow blender version

yes, this is not a but, after changing mantaflow gas cache type from default to `Replay`, `quick smoke` simulation work as in previous not mantaflow blender version

@dark999 You're right. The manual is still work in progress so this isn't properly documented yet.

Thanks for this. Works. Well ... not realtime anymore. ;-)

OK, set Resolution Divisions to 16. ;-) Love 2.82 btw. Amazing progress.

hi guys, ok so I'm seeing the same issues as you guys with this. Simulations are pretty slow and by default Modular does not render anything. I was starting to worry that it was locally only. Looking forward to seeing that working! Keep up the amazing work on this app, gang!
